SELF-WAITING TABLE.

To all whom it may concern.

Be it known that I, CAR NILSON, a citizen of the United States, residing at ElOI'O, 1I1 the county of Clearwater and State of Mlnnesota, have invented new and useful Improvements in SelfW'aiting Tables, of which the following is a specification.

This invention is an improved self-waiting table providing a revoluble member 1n the top, means to operate the revoluble mem- 1 is a vertical sectional view of a self-waiting table constructed in accordance with my invention. Fig. 2 is partly a plan and partly a horizontal sectional view of the same on the plane indicated by the line aa of ig. 1. Fig. 3 is a horizontal sectional view on the plane indicated by the line bb of Fig. 1. Fig. A is a detail view.

The frame of the table is indicated at 1, the supporting legs at 2 and the top at 3. The top is here shown as provided with a circular central opening and as circular in form. The apron l of the table is circular in form and extends downwardly from the top, near its outer edge. The supporting legs pass through the corners of-a lower shelf 6.

A casing 7 is arranged and secured on the center of the shelf 6 and is provided at one side with a hinged door 8 which has an opening9. A spring motor 10 is secured on the center of the shelf 6 and in the bot tom of the casing. This motor includes a vertical driving shaft 11, a winding shaft 12, an escapement wheel 13 and an anchoring escapement 14. The spring motor may be of any suitable construction and the winding shaft 12 thereof, which is horizontally arranged, has its outer end opposite the opening 9 in the door 8 so that a winding key 15 may be inserted through said opening and applied to the winding shaft Specification of Letters Patent.

the spring. A train'of gears connects the winding shaft with the vertical driving shaft 11, another train connecting said shaft with the shaft of the escapement wheel. The upper end of the driving shaft is squared or of non-circular form.

A tubular standard 16 has outturned feet 17 at its lower end which are secured on the upper side of the frame 18 of the motor. In the upper end of the tubular standard is a bearing 19. J

The table top has a revoluble circular member 20 arranged above the central opening and provided with a vertical supporting shaft 31 which extends centrally therethrough, is mounted in the bearing 19 and the lower end of which is telescopically fitted on the upper end of the driving shaft 11 so that the member 20 is adaptedto be if to enable-the latter to be turned to windup revolved by the motor. The shaft 21 also extends above the member 20 and carries a revoluble member 22 which is spacedv asuit-' able distance above the member 20. The

shaft 21 has alocking spur wheel 23 which is 1 arranged above the standard 16. A circular frame 24 is arranged above the standard and is connected thereto by bracket arms 25 which serve to support said circular frame.

The frame is also connected to the side walls of the casing by means of radially arranged arms 26 each of which comprises an inner member 27 and a tubular member 28 the latter being mounted for rotation in an opening in one of the side walls and having threaded engagement with the inner member. These radial arms are thus adapted to be adjusted longitudinally and enable the standard and the shaft 21 to be held in a perfectly vertical condition. A pair of arms 28 project horizontally from opposite sides of the standard 16, near the upper end of said standard and a pair of tubular arms 29 also project from the standard, below the arms 28. Vertically arranged detents 30 are pivotally mounted in the arms 28 andhave their lower ends extended through slots in the upper sides of the tubular arms 29. Springs 31 are arranged in said tubular arms and press the lower ends of said detents outranged a suitable distance apart. A main operating cord 33 engages the outer sides of all of the pulleys 82 and engages the inner sides of the pulleys 31 and normally this cord is sufliciently slack to enable the detents 30 to be kept in engagement with the locking wheel 23 by their. actuating springs. Branch operating cords 34 are attached to the main operating cord at various points and are arranged radially and lead outwardly from the main operating cord and through openings in the walls of the casing to the apron t of the table, said branch operating cords passing through openings in the apron and each being provided at its outer end with a ring or other pull device 35. Any suitable number of these branch operating cords may be provided.

Ordinarily the member 20 of the table top is stationary. When, however, any one of the cords 34 is pulled by a person seated at the table the main operating cord 83 is tightened and caused to draw the detents 30 outwardly so that they disengage the looking wheel 21 and thereupon the motor turns the shaft 21 with the table members 20 and 22 so that the dishes on said table members will be brought successively before every one seated at the table and the persons at the table may readily help themselves. As soon as the branch operating cord which has been pulled is released, the detents rengage the locking wheel thus checking further rotation of the revoluble table top members.

Having thus described my invention, I claim 7 l. A table of the class described comprising a bottom and top member disposed in spaced relation, supporting legs connecting the said members, a motor supported upon said bottom member, a standard rising from the motor, a vertically disposed rotatable shaft connected with said motor and projecting through the standard and said top me1nher, an auxiliary table top fixed upon said shaft for rotation therewith, a locking wheel on said shaft, tubular extensions projecting from the opposite sides of said standard, pivoted arms having terminal otl'set portions positioned within said tubular extensions, springs arranged within said extensions and bearing against said offset portion of the arms to hold the latter in engagement with said wheel to hold the auxiliary table member against rotation, and means associated with said arms to effect a release of the latter to permit rotation of said table member.

2. A table of the class described comprising a bottom and top member disposed in spaced relation, a casing fitted between said -members, a motor arranged within the frame and supported upon the said b ttom member, a rotatable shaft connected with the motor and projecting through the said auxiliary table top fixed upon said shaft for rotation therewith, a locking wheel on said shaft, pivoted spring pressed arms normally engaging said wheel to provide rotation of sald auxlliary top member, pulleys on the upper ends of said arms, a ring disposed within the casing and adjustably connected with the walls thereof, said ring being concentrically disposed about said shaft, pul leys rising from said ring at diametrically opposite points, and an operating cord trained over said pulleys on the ring and said arms for moving the latter out of engagement of said wheels to permit rotation of said auxiliary table top.

In testimony whereof I atlix my signature in presence of two witnesses.
